摘要： Bypass assembly 100 includes stinger 150 received by receptacle bore 172 of tubular receiver 120 attached to tube 106. Bypass pathway 140 connects stinger port(s) (158, 158′) to slip hanger 122 supported hydraulic conduit 108 to bypass the tube 106. Tube 106 can be a subsurface safety valve or hydraulic nipple anchored within production tubing. Bypass assembly 200 includes upper 202 and lower 203 hydraulic nipples in production tubing 210, with respective tubular anchor seal assemblies (220, 230) engaged therein. Bypass pathway 214 connects hydraulic conduit 208 to slip hanger 242 supported hydraulic conduit 216 to bypass tubular anchor seal assemblies (220, 230). Bypass assembly 300 includes upper 302 and lower 303 hydraulic nipples in production tubing 310, with respective tubular anchor seal assemblies (320, 330) engaged therein. Bypass passage 318 connects stinger 350 to slip hanger 342 supported hydraulic conduit 316 to bypass tubular anchor seal assemblies (320, 330).

摘要： Presented is a subsurface safety valve in which the flapper mount, hard seat and spring housing have been integrated into a single assembly. To accommodate a “soft seat insert,” a special retainer soft seat ring and soft seat seal are provided. The soft seat seal fits over a conical protruding surface (hard seat) that surrounds the main bore of the safety valve on the bottom side of the spring housing. The retainer ring fits over the soft seat seal and holds it in place against the conical surface. Notches along the perimeter of an upper flanged end of the soft seat seal prevent gases, such as nitrogen, from becoming trapped behind the seal and potentially damaging it during a rapid decompression event. A gap between the upper flanged end of the soft seat seal and the lower spring housing allow the seal to move up and down the conical protruding surface as the flapper opens and closes, reducing compression of the seal and the risk of a compression set due to repeated opening and closing of the flapper.

摘要： The present invention is directed to a method and apparatus for providing a pathway for fluid communication through a tubing-retrievable subsurface safety valve (TRSSV). The method and apparatus are designed to be deployed within a hydrocarbon wellbore after the TRSSV has failed. The apparatus is a milling tool that is run into the wellbore and landed within the TRSSV. The milling tool comprises a housing system, a cutting system, a drive system, and an actuating system. In operation, the milling tool is landed within the housing of the TRSSV. Thereafter, the actuating system is initiated. The actuating system actuates the drive system, which in turn drives the cutting system. In one arrangement, the cutting system includes blades for shaving the pressure containing body of the TRSSV, thereby forming a pathway for fluid communication between a hydraulic fluid line and a bore of the safety valve.
